0 Atk Gliscor Earthquake vs. 252 HP / 0 Def Aegislash-Shield: 146-174 (45 - 53.7%) -- 34% chance to 2HKO

+2 252+ Atk Aegislash-Blade Iron Head vs. 244 HP / 0 Def Gliscor: 262-310 (74.4 - 88%) -- guaranteed 2HKO after Poison Heal

Gliscor won this, but it is still not a perfect counter. If it is a 1v1, Gliscor won this for sure. However, with a bit of prior damage, it can still lose to Aegislash. Also, Gliscor is not a Meta-defining pokemon. Poison Heal Gliscor usage is lower than 1% in PBB. Therefore, Aegislash does not suffer much from this. It is like "Clefable is bad because Steel type exists, or Mega Salamence is bad because Ice type exists". Those arguments are invalid.
